The quicksilver dragon has a mercurial personality, often going from playful to pugnacious for no apparent reason. Despite their great bulk, they are deft swimmers -- although most of the time they float at the surface waiting for their next meal to swim by. While tending a Water Habitat, a 'log' turned out to be a hungry Quicksilver Hatchling and a young wizard inadvertently invented a "Run on Water" spell.

The game description's use of the word "mercurial" is likely a reference to the fact that quicksilver is another word for the element mercury.

The goal completion text for hatching a Quicksilver Dragon references the phrase "mad as a hatter". This is relevant to the Quicksilver Dragon as the origin of this phrase is that mercury/quicksilver was at one time used in the production of felt hats, and poisoning from the toxic metal accumulating in their bodies would often turn the workers insane.
